To all whom it may concern:

Bejit known that I, RoBnR'r- HEAD, a citizen of, the United States, residin at New York, in the county and State of ewYork, have invented certain new and useful Improvements in Phonographs with Extensible Horns, of which the following is a specifi cation.

My present invention relates to, a phonegraph with an extensible horn, the features and advantages of which will be apparent to those skilled in the art from an understanding'of the following description in connection' with the drawings, showing one of the specific embodiments-my invention In the drawings Figure 1 is a vertical section partly in side elevation of a cabinet-ed phonograph embodying my invention and showing the horn extended; Fig. 2 is a horizontal section partly in plan takenbelow the motor-board in Fig. 1;.Fig. 3 is e-"vertical section through the front portion of the instrument showing the mouth-section of the horn telescoped back into the cabinet; Fig.

i is a partial face view, of the door p'ortion of the cabinet, the left hand portion of the doors being broken away to disclose the mouths of the two horn-sections; Fig.5 is an enlarged vertical section partly in tie-- vation to show the structure of the doorlocking means; Fig. 6 is a vertical sectional view indicating the relationship between the horn-sections when sliding on each other;

Fig. 7 is the same indicatin their relationship when interlocked; and ig. 8 is a partial plan view of the interlocked horn-sections partly in horizontal section.

Describing now the devices of the drawings:-l is a phonograph cabinet, 2 the sound-box and tone arm, 3 the deck or motor-board, 4 the turn-table. and 5 the motor. The horn consists of a main section 6 within the cabinet and amouth-section 7 outside but adapted to be telescoped into the cabinet when not in use. The mouth section is mounted in a box-like. frame 8 sliding in a rectangular. opening in the front of the cabinet. 9 is a tail-piece extension (Figs. 1 and 2) from said frame sliding through an openlng l0. incross-bar 10 in the cabinet to prevent the front of the IIIOUKlI'SECl-lOD. and its frame 8 from dropping or sagging as it is withdrawn from the cabinet and also to guide said mouth-section to prevent it from jamming as it is slid in and out.

' The main horn section has rcarwal'dly turn-backed flanges 11 atits month which are divided from each other at the corners so as to be springy and form a tight fit when received into a collar-like extension 12 on the back of the lllOlltlPSGCtlOll 7. This collar has an inwardly directed flange l3 preventing the mouth-section from i being pulled awuv from or ofl the Main-section. The bottoms of the two horn sections are substantially parallel to the sliding direction of the w aith-section In other words, in. the particular embodiment shown, they are fiat and ordinarily would slide in contact with each other so that the bottom of the mouth while the mouth-section is being slid in and.

' out; On the other hand, the collar 12 is so inclined to the flanges 11 that they coeperate, when the mouth-section is forced into out-position, not only'to make a tight joint between themselves but also lift the bottom of the mouth-section into snug contact with the bottom of the main section. In short "the joint'between the two horn sections is rendered tight'all around to the improvement of the acoustic quality of the total horn. g i

It will be further noted that the joint made by the parts 11 and 12 between the horn-sections. is such (see Fig. 7) that the sides ofthe mouth-section continue the sides of the main-section without any abruptness in the joint-which again is to the improvement of the acoustic quality of the total horn. v

When the mouth-section is in its out-position, means is provided for releasably looking it in that position as follows :--1 i is a piece having its front end pivoted at 15' to ship the parts constituting the joint between the two horn-sections. The parts 14,15 and 17 are duplicated on both sides of the horn; and both pieces 1 1 have downwardly extending operating-arms 18 united at their ends by a crossrod 19. 20 is a rod slidably supported on the bottom of the frame 8, its 1nner end being pivotally connected wlth the cross-rod 19 and its outer end bemg provided with a hand-piece orknob 21 (see Figs. 1 and 2). When the mouth-section is locked rigidly in outposition as shown in these figures and it is desired to release the locked union betwen the horn-sections and telescope the mouth section. back into the cabinet, this is simply accomplished by pushing inwardly the knob 21 because this tilts upwardly the pieces 1 1 until their bottom edges clear the tops of the pins 17, whereupon continued pushing on the knob slides the mouth-section back into the cabinet. Reversely pulling outwardly on this same knob 21, pulls out the mouth-section of the horn and when in its out-position, the final pull on the knob wedges the ends 16 of the pieces 14 down against the pins 17 which forces and locks together the two horn-sectionswith a ti ht joint, as described, between them.

The frame of the mouth-section has a rectangular opening in it corresponding to the mouth of said section, and carries a door 22 (Figs. 1 and 1) hinged to it at 23. This door 22 is compound, in that it embodies a second smaller door, illustrated as a grille 24, adapted to be independently opened on its own hinges 25 (Figs. 3 and 1) to leave an openin r corresponding to the mouth of the main iorn section. The surrounding part of the door being closed while the grille is open (compare Fig. 3) eliminates unsightliness by preventing looking into the cabinetoutside the mainhorn.

Finally automatic door-locking means is provided -whereby When the horn-sections are extended as in Fig. 1, pulling on the door-knob 26 will open the entire compounddoor as a unit because the grille door 24; is then automatically locked in the frame 22 so that the two must carry together. This therefore opens up thefull mouth of the mouth-section of the horn which is just what is wanted when this section is in use. On the other hand, when the mouth-section is telescoped into the cabinet out of use, the door frame 22 is thereby automatically locked in shut position, so that pulling on the same door-knob 26 (of. Fig. 3) can only open the grille-door 21, which is just what is wanted because this opens up the mouth of the main horn-section which is now alone in use.

The detail means by which I accomplish this is shown in one of its forms in Fig. 5. As shown, the top-board of the frame 8 of the mouth-section, the door frame 22, and the top of the grille-door 24, all contain alined vertical holes housing respectively its lower end enters the mouth of the hole in door-frame 22 as in Fig. 5 preventing it from being opened by pulling on the doorknob 26, which accordingly opens only the grille door 24. On the other hand, when the mouth-section is out, the plunger 27 springs upwardly, unlocks the door-frame 22. Further this permits the plunger 28 to rise under the lifting action of the springpressed plunger 30 whose nose therefore enters the hole in the door-frame 22, thereby locking together said frame and the grilledoor so that they now carry asone door to open the large mouth of the extended horn.

lVhat I claim is 1. In a phonograph, the combination ofa cabinet, a horn comprising a mouth-section and a main section, the main section being located inside the cabinet, and the mouth section outside but beingtelescopable into the cabinet when not in use, the mouth section in out-position being adapted when forced outwardly to form a substantially tight joint with the main section, and releasable means for forcing the mouth section outwardly as aforesaid.
